Repeat for subsequent block erasures.
Full status check can be done after each block erase or after a
sequence of block erasures.
Write FFH after the last operation to place device in read array mode.
SR.5, SR.4, SR.3 and SR.1 are only cleared by the Clear Staus
Register command, in cases where multiple blocks are erased before
full status is checked.
If an error is detected, clear the status register before attempting retry
or other error recovery.
